There’s more to a roof than just wood and some shingles, there are other small parts and pieces that make up a roofing system. These lesser known pieces each play a key role in making sure a roof can hold up against Mother Nature and making the system as a whole lasts for a very long time. One of these important, but lesser known pieces — roofing felt.
What is Roofing Felt?
Roofing shingles aren’t just nailed to the wooden sheathing — roofing felt is a material that is installed as a buffer between the two. Also called tar paper, roofing felt is typically a sheet of fiberglass fleece that is covered in a waterproofing coating. These large sheets of “paper” are installed to help protect the structure of your roof beneath the shingles.
What Does Roofing Felt Do?
Shingles can become damaged, cracked, and even go missing over time. Roofing felt is applied between the shingles and sheathing to protect the wood from becoming water damaged, in case water or snow finds its way underneath these shingles. This material is applied across the entire roof, whereas a material like flashing is only installed near chimneys, roof intersections, etc.
How is Roofing Felt Installed?
Roofing felt can be purchased in large rolls, usually 36 inches in width. Installation should start at the bottom of the roof, working your way up until the entire roof is covered. It’s installed this way so that if any water makes its way to the roofing felt, it can roll down the material without fear of it getting between the seams. However, this material is better off being installed by expert installers, as any gaps and wrinkles can be critical to the health of your roof.
